19.7. Example: Decoupling of Branches
Buffer energy supplied from a DC UPS or buffer module is not wasted in “power branches.”
Please note:
Set output voltage of the power supply to a level sufficient to prevent the buffer unit or DC UPS from starting
unexpectedly. Take the voltage drop of the 1606-XLERED into account.

19.8. Use in a Tightly Sealed Enclosure
When the redundancy module is installed in a tightly sealed enclosure, the temperature inside the enclosure will be
higher than outside. The inside temperature defines the ambient temperature for the redundancy module.
Results from such an installation:
Power supply is placed in the middle of the box; no other heat producer is inside the box.
Enclosure: Rittal Typ IP66 Box PK 9516 100, plastic, 110x180x165mm
Load: 24V, 16A; (=80%) load is placed outside the box
Input: 24Vdc
Temperature inside enclosure: 58.8°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 24.6°C
Temperature rise:
34.2K
